Creating a clone of #6371 for diagnostic purposes. See #6365 (again).

Some recent DMA changes have led to data loss in UART0 on Pi 5. It also
seems that even prior to these changes there was a problem with aborted
transfers.

As this is the only RP1 UART configured for DMA, it is better to remove
the DMA usage until it is shown to be reliable.

I guess this has been superseded by #6742 ?
